Multi-user clustering and viewpoint calculating system and method based on multiple three-dimensional pictures

The invention discloses a multi-user clustering and viewpoint calculating system and method based on multiple three-dimensional pictures. The system comprises an infrared capturing module, a position mapping module and a real-time clustering module, wherein the infrared capturing module is used for obtaining the position information of a user, and tracking users in real time, the position mapping module is used for mapping physical coordinates of the infrared capturing stage to the virtual space coordinates, and the real-time clustering module performs real-time dynamic clustering on virtual space users according to user distribution characteristics, takes the central position of a clustering block as viewpoint information of the users, and provides data for follow-up picture rendering. Under the condition that the number of audiences exceeds that of displayed pictures of the system, the audiences with the large position difference can watch the three-dimensional pictures of different viewpoints on the same p
